FIELD: tumor immunotherapy.
SUBSTANCE: Fab fragment of an anti-VEGF antibody is provided. An isolated Fab fragment of an anti-VEGF antibody contains a heavy chain variable region containing a CDR1 region of the following SEQ ID NO: 27, CDR2 with the following SEQ ID NO: 28, CDR3 with the following SEQ ID NO: 29; and a light chain variable region comprising CDR1 region of the following SEQ ID NO: 24, CDR2 with the following SEQ ID NO: 25, CDR3 with the following SEQ ID NO: 26. Also the following is proposed: a conjugate containing an antibody Fab fragment and a therapeutic agent, a nucleic acid encoding an antibody Fab fragment, an expression vector, a host cell, a method of producing an antibody Fab fragment, a pharmaceutical composition and a combination, and a method of treating an angiogenesis-related eye disease. The Fab fragment of the antibody effectively blocks the activity of VEGF165.
EFFECT: inventions can be used to treat eye diseases characterized by choroidal neovascularization, including age-related macular degeneration (AMD), diabetic macular edema (DME), retinal edema, degenerative myopia, choroidal neovascularization (CNV).
